Companies with strong data warehousing and/or business intelligence exposure are the hardest-hit by Informatica's (INFA -28.3%) Q2 warning. QLIK -14.4%. MSTR -10.1%. TDC -10.2%. BofA is downgrading Informatica to Underperform, and thinks the warning indicates sales execution problems, competitive pressure, and "potential structural issues in the data integration market." Jefferies is also downgrading, but only sees Informatica's problems as demand-related.
